The Lunar Meteoroid Impact Observer (LUMIO) mission was proposed by a consortium including Politecnico Di Milano (IT); TU Delft (NL); École Polytechnique Fédérale de Lausanne (FR); S[&]T Norway (NO); Leonardo S.p.A (IT); and the University of Arizona (US).
LUMIO is a CubeSat mission to a halo orbit at Earth–Moon L2 that shall observe, quantify, and characterise meteoroid impacts on the Lunar farside by detecting their impact flashes, complementing Earth-based observations on the Lunar nearside, to provide global information on the Lunar Meteoroid Environment and contribute to Lunar Situational Awareness.
The Lunar Volatile and Mineralogy Mapping Orbiter (VMMO) was proposed by a consortium including MPB Communications Inc. (CA); University of Surrey (GB); Lens R&D (NL); and the University of Winnipeg (CA).
